I have removed the link to the YouTube video. The topic can remain, as it is worthy of discussion as to how poor and disrespectful behaviour this is, but this Youtuber is not going to profit from hits on this silly video because it was seen here. This is not the first such video this person has done, but you know what, please don't search them, it just looks like people are validating this idiocy if he gets more hits. He's hoping for the "any publicity is good publicity" effect, let's deny him that!
I think that the pilot should be ashamed on several fronts. Deliberate, wasteful destruction of an airplane which someone built and maintained with care is one. Be should be made to repair the plane to the condition in which he flew it, maybe after that, he'd learn some respect for something someone built with care....
